Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed September 22, 1919. Serial No. 325,887.

To all whom it may concern:

Be it known that I, LoUIsGREnNBnno, a

citizen of the United States, residing at- Figure 1 is a verticalsectional view of adevice constructed in accordance with my invention;

Fig. 2 is a sectional view taken through the container on line 2-2 ofFig. 1;

Fig. 3 is a horizontal sectional view taken on line 33 of Fig.2;

Figs. 4 and 5 are vertical sectional views taken on lines 4.-1 and 55,respectively, of Figs. 1 and 2; and

Fig. 6 is a diagrammatic view to be hereinafter referred to in detail.

As shown in the drawings, the device of my invention, comprises a basemember 1, preferably made flat and circular and havmg an upturnedmarginal flange 2, from which are bent portions 3 to provide feet forsupporting the device above the floor or other underlying support.Extending up .ward from the center of the base member 1 is a post 4,cylindrical in shape and having its lower portion screwed into anupright, tubular boss 5 with which the base member is provided. Thelower threaded end of said post 4 extends beneath the base member 1 andreceives a clamp nut 6 for locking the post against turning and endwisedisplacement. The upper end of said post 4 is reduced and extends abovea housing 7 secured to the marginalflan e 2, by fastening members a8.Said post 4 as its 11 per end bifurcated to provide a vertica slot 9therein, with the upright side portions 10, 10

thereof laterally spaced apartto receive a rectangular block 11 pivotedbetween said side portions by a pin 12. Surrounding said 0st 4 is asleeve or rotative member 13 havmg its upper end ing 7 and there rovidedwith an outwardly extendin annu ar flange 14, made flat and arrange atan inclination to the vertical axis of rotation of said sleeve. of saidflange 14 are in said inclined plane.

projecting above the hous- All portions" Located above said flange 14 isa plate 15 made flat and circular and preferably having a diametergreater than said flange 14 and arranged concentric therewith. Saidplate 15 is inclined to the same extent as said flange and is tiltablyconnected with the upper end of the post 4 in the following manner. Theplate is provided, adjacent its center, with two downwardly extendingcars 16, 16, preferably formed by being bent out of the body of theplate, as shown in Fig. 4. The ears 16 are alike and are laterallyspaced apart to receive therebetw'een the block 11 which is connectedwith said cars by pivot members 17, 17. The u per end of the sleeve 13opens through 1; e flange 14 from beneath, to permit the ears 16, 16 toextend planes at right-angles to each other. Interposed between theflange 14 and the plate 15 are a plurality of rollers 18, 18, permittingthe fiange to be rotated easily beneath the plate. As shown, saidrollers are carried by the flange 14 and are arranged with their treador rolling surfaces projecting above the flange and in rolling contactwith the under side of the plate 15, the latter thus in effect restingon said rollers. Three rollers 18 are employed, as shown in dotted linesin Fig. 2, and are spaced apart circumferentially equal distances, sothat the plate will properly engage the flange 14. In the constructionshown, the rollers 18 are located in vertical slots provided in theflange 14 adjacent its outer edge and each roller is held in position bya fastening screw 19 extended through the roller and the outer edge ofthe flange.

Removably mounted on the late 15 is a container or receptacle 20 proerably made of metal and circular in shape, and concentric with saidplate. Said container has an upright outer wall 21, a flat bottom wall22, and a top wall 23 having anopening centrally arranged and closed bya removable cover 24, provided with a handle 25 on the outsidethereoflThe container is also provided with handles 26, 26, secured to the unightwall 21 on the outside thereof to faci tate lifting and handling ofsaid container. The container is provided with a plurality of internalribs 27, 28, the former on the 85 low the point 0 of pivotal connectionbe-J side wall 21 and extending between the top and bottom walls, andthe letter on the bottom wall 22.

For rotating the sleeve or rotatably mounted member 13, I provide a wormgear 29 secured by screws 30 to the lower en of said sleeve, there beingan antifriction hearing 31 interposed between said gear wheel and theupper end of the part 5. Located in the housing 7 is a motor 32, thearmature shaft of which is horizontally arranged and provided with aworm 33 in mesh with the worm gear 29.

The container is detachably connected with the plate 15, so that it maybe removed completely from the mechanism to facilitate the filling andemptying of the same and also for cleanin purposes. As shown, the plate15 is provided at its outer margin with two circumferentially s acedcars 34, 34, integral with the plate an bent upwardly and inwardly toengage over an outwardly projecting, annular flange 35 at the "bottom ofthe container. The plate 15 is also provided on its outer margin with alug 36 integral with and bent upward from the plate to receive a setscrew 37, the inner end of which engages over said flange 35, as shownin Figs. 1 and 2. By withdrawing the screw 37 from its engagement withthe flange 35, the container 20 may be readily and easily removed fromthe late 15.

The device shown and descrlbed, operates as follows: When used as awashing machine, the articles of clothing or other fabrice to be washed,are placed in the container, to ether with the required amount of wateran soap or other washing ingredient, and the cover 24 is ap lied toclose the container. The latter is t on placed on and secured to theplate 15, or the container may be first applied toithe plate and thenfilled. The motor 32 is then started by turning on the current, and asthe motor 0 crates the rotating member or sleeve 13 an its flange 14 arerotated in one directiomwhile the post 4 and its connected container 20are not revolved in a horizontal plane. As the inclined flange 14rotates beneath the container, the latter is tllted up and down inintersecting vertical planes at right-angles to each other and passingthrough the axis of rotation of said flange 14 during each revolution ofthe lat ter, thereby agitating the water in the container and effectinga washing "of the fabric articles.

In order that the type of motion imparted to the container may be morefully under-- stood, let it be assumed that the parts occupy thepositions shown in full lines in Figs. .1 and 6, when the motor isstarted. As the inclined flange 14 is revolved, the lowermost point a onits outer edge is carried around in a horizontal plane 12, which isbetween the post 4 and the container. The highest point a? of saidflange 14 15 carried around in a horizontal plane 6 parallel with theplane b and above the pivotal point e. Thus,when the flange 14 has beenrevolved 180 from the starting point mentioned, said flange is in theposition shown by the dot and dash lines .9 in Fig 6. As the point (1moves toward the rig it, from its position shown in full lines in Fig.6, the container tilts on the ins 17 toward the plane b, and when thepoint a reaches a. position 90 from its starting point, the containerhas been tilted into the position shown by the dotted lines 0 in Fig. 6.When the point a reaches a point diametrically opposite its full lineposition, the container tilts on the in 12 to the position shown by said0t and dash lines q. When the point a reaches a position 270 from thestarting point mentioned, the container tilts again on the pins 17 andoccupies a position shown by the dotted lines r in Fig. 1. When thepoint a. has made a complete revolution, it is brought back to itsstarting point. The container tilts gradually as the inclined flange 14revolves, and progresses from one tilted position to another in therotation of said flange. In each complete revolution of the latter, thepoint It on the lower edge of the container is moved up and down in theare i of a circle, the center of which is the pivotal point a, While thepoint j on the line m in Fig. 6 passes through the center of thecontainer and the pivotal point 0 when the container is in the tiltedposition shown in full lines; the line 11. passes through said point aand the center of the container when the latter is in the tiltedposition shown by dotted lines 0 and the line 10 passes through saidpoint 0 and the center of the container when the latter has been tiltedto the position shown by the dot and dash lines 9'. The

upper and lower lines f, g, define the extreme distance that thecontainer is tilted.

A device made as described, is com act, as

all of the operative parts are below t e container, and the weight beingbelow the container, the device is prevented from upsetting as thecontainer is tilted. By providing the container with ribs 27, 28 andtilting the container rogressively as the flange 14 revolves, sufiicientagitation is given to the water and articles in the container to makethe washin thorough and rapid.
